As part of the update, the app adopted a feed powered by algorithms (like Twitter, Facebook, and Instagram before it), which showed you content from the users you watched and interacted with the most at the top.

Meanwhile, it dumped celebs and media publishers in a separate tab away from your mates to avoid clutter.

Social networks generally implement these types of changes to increase the time you spend on their apps, as you're forced to scroll through feeds to find fresh posts and left switching tabs to access different types of content.

And the more time you spend on a platform, the more money it can make from marketers keen to show you ads.

But now Snapchat has switched up its feed for some users, and while it has left some elated, no one is really sure why.

Is it a test or part of a wider rollout? We've reached out to Snap (the app's parent company) for comment.

It doesn't seem like a response to the backlash from its redesign, which has long since fizzled out.
